I have a master degree in Cognitive Artificial Intelligence and specialized in Human Computer Interaction. That's the reason I choose GUI Junkie as my on-line personality (GUI stands for Graphical User Interface).

My wife is a psychologist.

Thanks to cooking.stackexchange I'm becoming a better cook, and, to give something back, I've posted a number of improvement suggestions at MSO, resulting in four (!) question bans in one year (these have all been lifted).
